                IABIndexParser

A concrete Publisher that parses IAB (Individual Address Block) records from IEEE text-based registration files

It notifies registered Subscribers as each record is encountered, passing on the record's position relative to the start of the file (offset) and the size of the record (in bytes).

The file processed by this parser is available online from this URL :-

http://standards.ieee.org/regauth/oui/iab.txt

This is a sample of the record structure expected:

   00-50-C2   (hex)        ACME CORPORATION
   ABC000-ABCFFF     (base 16)        ACME CORPORATION
                   1 MAIN STREET
                   SPRINGFIELD
                   UNITED STATES
